Specs and even Examine of Hyundai Sonata Hybrid Vehicle
The Hyundai Sonata Hybrid, expected to hit dealerships later this kind of 12 months, is certainly the South Korean company's first hybrid inside the US marketplace. Apparently, Hyundai took its time, scrutinized the hybrid competitors, as well as attempted to outdo it in each and every respect. At a price beneath $26,000, Hyundai has generated a mainstream mid-size hybrid sedan that delivers actual competition for class-leading fuel economic system. Hyundai expects the Sonata Hybrid to achieve 37 miles per gallon in the metropolis and also 39 mpg on the highway.
Since the motor is certainly synced straight to the transmission, a clutch latches to along with unlatches in the gasoline-fed 2.4-liter inline-four with 166 horsepower plus 154 pound-feet of torque on tap (also revised slightly from before in the yr). As you'd expect from a hybrid, the Atkinson-cycle variant from Hyundai's Theta II household continues to be optimized meant for maximum effectiveness. Last mixed efficiency figures are 206 horsepower along with 193 pound-feet of torque.
Hyundai engineers say the lithium-polymer batteries can tolerate tens of a large number of charge cycles, with out possessing to make use of a liquid-cooling system. According to W. C Yang, president in the Hyundai R&D Center, the Sonata Hybrid batteries should supply "300,000 miles with less than 10 percent reduction in efficiency . that's purely from an engineering point of view, not a warranty point of view." Hyundai currently provides a 100,000 mile/10 yr powertrain warranty inside the U.S. market.
Also enhancing highway mileage is certainly an Atkinson-cycle version of your 2.4 Theta II engine, based on the standard 2.4-liter engine inside the Sonata, but recalibrated to run on the Atkinson cycle, a common way of improving the efficiency of engines used in hybrids. A fair amount of low-end torque is actually sacrificed inside the Atkinson conversion, but that is certainly made up by the addition of torque from your electric motor. Combined, the engine and electric motor generate 209 hp and even 195 lb-ft of torque, compared to 198 hp/184 lb-ft from your 2.4-liter version standard within the Sonata.
The multi-disc clutch pack sits inside the motor as well as is certainly used to decouple the 2.4-liter engine for idle/stop and electric-drive modes. By allowing higher EV-only speeds, the clutch plays a big part in the Sonata's highway fuel efficiency. With a 17.2-gallon fuel tank, the Sonata Hybrid has a theoretical range of 766 miles.
